Hi,
I’m trying to change process version from history dropdown but it always present the latest one.
Does anyone use this version control and know if there is any workaround ?
I’m using Flowable-modeler 6.3.1
It looks like version is changed under the hood (but it shows latest one) cause when I click version 2 or 1 of my process and then try to download process definition I receive the following issue:

So it’s fixed 
but does it also fix the issue with version changing ?
I think that there was no problem with the version changing. Only with how it was retrieved, and that was not working . Try to hit the endpoint from the browser with the correct path and it should be there
Nope. It doesn’t work or I missed something ;(
I’ve recorded current behavior https://streamable.com/nll22
Do you have any idea what is going wrong ?
Thx.
Hi,
From your screen capture I would say that there is a bug in the history selection. Could you create an issue on Github with a link to the screen capture? Then we can track it and make sure it gets resolved.
Best regards,
Tijs
